One day while travelling, a young thief named Gareki saves Nai from a monster and takes an immediate interest in the trinket he carries, as it is the insignia of Circus, an elite group who travels the world capturing notorious criminals. Together, the two decide to track down Circus and see if they’ve taken Karoku, but luckily, the group finds them first. Unfortunately, they have no idea who Karoku is or why he had one of their identity bracelets, but in the hopes of getting to the bottom of the matter they offer their assistance. Now, Nai, Gareki and their new friends set forth to find Karoku, but with more questions piling up each day will it be possible to achieve their goal?
